KTechlab is a development and simulation environment for microcontrollers and electronic circuits, distributed under the GNU General Public License.

KTechlab consists of several well-integrated components:

- A circuit simulator, capable of simulating logic, linear devices and some nonlinear devices.- Integration with gpsim, allowing PICs to be simulated in circuit.- A schematic editor, which provides a rich real-time feedback of the simulation.- A flowchart editor, allowing PIC programs to be constructed visually.- MicroBASIC; a BASIC-like compiler for PICs, written as a companion program to KTechlab.- An embedded Kate part, which provides a powerful editor for PIC programs.- Integrated assembler and disassembler via gpasm and gpdasm.
